Great. However, how to use it?
I've modified my schema to look like below:
In java, when I try to parse this schema with:
Schema usersSchema = Schema.parse(USERS_SCHEMA);
I get an "org.apache.avro.SchemaParseException: No type" exception
(Here USERS_SCHEMA is the schema below).
{
"name": "Users",
"type": {
"type": "array",
"items": {
"name": "User",
"type": "record",
"fields" : [
{"name": "name", "type": "string"},
{"name": "id", "type": "long"}
]
}
}
}
